Graphics / My texture holder gets deleted although still in scope

« on: June 13, 2019, 04:37:30 pm »

So I'm new to SFML. I read a lot of post, but I really  don't get it.
I wrote an texture holder:

class tile_texture_holder {
private:
   sf::Texture tx;
public:
   tile_texture_holder(type a) {
      switch (a) {
      case type::desert:
         tx.loadFromFile("C:/Users/Andreas/source/repos/conquer/Media/desert.png");
         break;
      case type::grass:
         tx.loadFromFile("C:/Users/Andreas/source/repos/conquer/Media/grass.png");
         break;
      case type::mountain:
         tx.loadFromFile("C:/Users/Andreas/source/repos/conquer/Media/mountain.png");
         break;
      case type::water:
         tx.loadFromFile("C:/Users/Andreas/source/repos/conquer/Media/water.png");
         break;
      }
   }
   sf::Texture ret_texture() {
      return tx;
   }

   ~tile_texture_holder() {
      std::cout << "///////////////////////HOLDER DELETED!!!/////////////////////" << std::endl;
   }
};

And I tried to load a sprite with it in different ways....
For example:

tile_texture_holder t(type::desert);
      sf::Sprite s;
      s.setTexture(t.ret_texture());

(in the same function, where I draw the sprite)
I always get the white box being drawn. And I really dont get why the texture_holder is getting deleted.
BTW type is an enum.

I hope somebody can help me solve my issue!

Window / Window doesn't finish loading and is not responding to input

Hello fellas!

I'm new to SFML so my problem is maybe stupid. I made a main menu and my problem is that if I start the program I get this loading mouse icon and the programm isn't responding to my input. The input is checked in another than the menu class so maybe thats my problem but I'm not sure.
Here's my code:

menu header:

(click to show/hide)

#pragma once

#include <SFML/Graphics.hpp>

class button {
private:
   sf::Texture bttex;
   sf::Sprite btspr;

   sf::Texture btctex;


   sf::Font font;
   sf::Text txt;

   sf::Mouse m;
   //font mit fkt set fonttext und wenn maus intersected && linksclick ausführen
public:
   

   button() {
      bttex.loadFromFile("C:/Users/Andreas/source/repos/jumpnrunSFML/Debug/Media/button.jpg");
      btspr.setTexture(bttex);
      btctex.loadFromFile("C:/Users/Andreas/source/repos/jumpnrunSFML/Debug/Media/buttonclicked.jpg");

      font.loadFromFile("C:/Users/Andreas/source/repos/jumpnrunSFML/Debug/Media/arialbd.ttf");
      txt.setFont(font);      
      txt.setCharacterSize(60);
      txt.setFillColor(sf::Color::Black);
   }

   void settxt(std::string s) {
      txt.setString(s);
   }

   void setpos(sf::Vector2f pos) {
      btspr.setPosition(pos);
      sf::Vector2f offset;
      txt.setPosition(pos + offset);
   }
   
   
   void draw(sf::RenderWindow &rw) {
      rw.draw(txt);
      if (btspr.getGlobalBounds().contains(sf::Vector2f(m.getPosition())))
         btspr.setTexture(btctex);
      else
         btspr.setTexture(bttex);
      rw.draw(btspr);
      rw.draw(txt);
   }

   bool clicked() {
      if ((btspr.getGlobalBounds().contains(sf::Vector2f(m.getPosition()))) && m.isButtonPressed)
         return true;
      return false;
   }

   sf::Sprite getSprite() {
      return btspr;
   }
};



class mainmenu {
private:
   sf::Texture backtex;
   sf::Sprite background;
   sf::RenderWindow menuscreen;

   button play;
   button exit;
   //button play("play", sf::Vector2f(0.f, 10.f));
   //button exit("exit", sf::Vector2f(0.f, 20.f));
   
public:
   mainmenu():menuscreen(sf::VideoMode(400, 800), "menu") {
      backtex.loadFromFile("C:/Users/Andreas/source/repos/jumpnrunSFML/Debug/Media/kp.jpg");
      background.setTexture(backtex);
      play.settxt("play");   play.setpos(sf::Vector2f(25.f, 50.f));
      exit.settxt("exit");   exit.setpos(sf::Vector2f(25.f, 200.f));
      
   }

   void run() {
      while (menuscreen.isOpen()) {

         
            
            if (play.clicked()) {
               menuscreen.close();
               return;
            }
            if (exit.clicked()) {
               exit;
            }
         
         menuscreen.clear();
         menuscreen.draw(background);
         play.draw(menuscreen);
         exit.draw(menuscreen);

         
         menuscreen.display();
      }
   }

};

main:

(click to show/hide)

#include "game.h"
#include "menus.h"

int main()
{

   mainmenu m; //menü
   m.run(); //menü
   return 0;
}

I hope somebody can help me. And yes, sorry for ugly code. I'm just playing around.
